If you need more pictures of the early JPL cluster computers, using acoustic and optical interconnects, let me know.. They’ve recently reorganized the photo archives here, and it’s a lot easier to find stuff (like pictures of the foundation of the building my office is in, from the 1950s, when they were digging it)
There’s also a story from Feynman of a pipelined compute chain using EAM equipment (EAM – Electric Accounting Machinery – readers, sorters, punches, programmed with plugboards) and human computers. You might be able to find pictures, but since the whole project was classified, it’s less likely – the pictures probably declassified 50 years later, but that doesn’t mean someone has spent the time and money to put them online anywhere.

It is quite helpful! I have a poster accepted for the Julia Conference in two weeks time. My proposal is to discuss computers just like that - on the Manhattan project etc. Then to show how Julia can easily be used to solve the equation for critical mass from the Los Alamos Primer. I havent done a damn thing for the poster yet.. ooops. I am also arranging a visit to Bletchley Park at the end of the conference. JuliaCon is sold out but I am sure you can watch the presentations http://juliacon.org/2018/ On Fri, 27 Jul 2018 at 15:06, Lux, Jim (337K) <james.p....@jpl.nasa.gov<mailto:james.p....@jpl.nasa.gov>> wrote: William Henry Dana – “Two Years Before the Mast” – An excellent book describing what it was like to be a sailor in the days just before steam, there’s plenty of climbing the rigging in a sleet storm, while trying to round Cape Horn. – but when they got to California, the weather was a lot nicer. Dana later went on to be a lawyer fighting for sailor’s rights. Silicon valley wasn’t very developed when Dana was doing his shipboard duties, and there weren’t any disk drives at the time. They *did*, however, have parallel cluster computing – rooms full of computers grinding out navigation tables. And I suppose they were commodity computers, using commodity interconnects (of the day), so could they fairly be called a Beowulf. https://www.theatlantic.com/science/archive/2016/06/the-women-behind-the-jet-propulsion-laboratory/482847/ describes a 1953 version of the same.

We have just the ship for it already. Powered by green energy, and built in Scotland of course. https://en.wikipedia.org/wiki/Cutty_Sark Just fill her hold with hard drives and set sail. Aaar me hearties. I can just see HPC types being made to climb the rigging in a gale...
